THE WHITE PINE BEETLE. 829 



considerably wider than long, and the sides are well rounded ; the sur- 

 face of the disk is slightly convex and covered with short linear chiti- 

 nous raised markings, which do not, however, form curvilinear lines, 

 except in a slight degree on the hinder edge, especially in the inverted 

 V' The V-shaped mark is much as in Chrysobothris. The raised mark- 

 ings on the disk differ decidedly from those of Chrysobothris in not 

 being round dots, but transversely linear in form. The apex of the V 

 is not inclosed in a square area, as in Dicerca, and the V is much nar- 

 rower. The disk on the under side of the prothoracic segment is much 

 as on the upper, the V being represented by a simple median line. A 

 pair of mesothoracic stigmata, and eight abdominal pairs. Head of the 

 same size as in Dicerca. Labrum much rounded on the front edge, and 

 much more contracted at the insertion in the fleshy clypeus than in 

 Chrysobothris. Antennae with the second joint a little longer than in 

 Dicerca, the third joint about one-third as long as the second joint, 

 tomentose and rounded at tip. Labium longer, fuller, more rounded 

 on the front edge, and a little narrower than in Dicerca, the edge not 

 being notched. It is more contracted at base than in Dicerca, and the 

 rudimentary palpi are more distinct than in Chrysobothris or Dicerca. 

 MaxiDfe a little slenderer than in Dicerca and Chrysobothris, three- 

 jointed J maxillary lobe much narrower, one-third less so than in Dicerca, 

 but not reaching beyond the distal end of the second palpal joint. The 

 two palpal joints are a little longer and slenderer than in Dicerca; first 

 joint much narrower than in Dicerca, the second joint conical at tip, 

 and as long as the first is thick. 



Entire length, 20'"™; length of prothorax, 3"""; breadth, 5"""; breadth 

 of eighth abdominal segment, 2.5'""'. 



This is not an Ancylocheira nor Anthaxia, according to Perris' figures, 

 but is related to Melanophila. Unlike the larvae of this genus, how- 

 ever, it has no " unguiform spine," but three equal radiating spines on 

 the tip of the lobe, while the lingula is entire. It can not be a Buprestis 

 (B. maculiventris) as it differs from Buprestis (Ancylocheira) as de- 

 scribed bj Perris, in the entire labium and the much longer labrum, as 

 well as the much shorter lobe of the maxilla and in the marking of the 

 prothorax. 



It occurred on the spruce at the Glen, White Mts., N. H., and under 

 the bark of spruce, at Brunswick, Me., August 27. 



11. Asemum moestum. 



We cut out from a spruce at Keene Flats, Adirondacks, a dead speci- 

 men of this species ; it probably not infrequently bores into this tree. 



12. The white-pine weevil. 

 Pissodes strobi Peck. 



This common weevil, which is described and figured on p. 734, we have 

 found the past season from the 10th to the 15th August, at Brunswick,
